and how could I apply this to a tal:repeat ?
I'd like to include some references to external javascriptfiles, if
they were set. For that, I created the following lines in my
template...
<tal:block tal:repeat="jsfile javascriptfiles">
<script type="text/javascript" src="${jsfile}"></script>
</tal:block>
however, if no javascriptfiles are set, this doesn't work.
I tried with
<tal:block tal:condition="exists javascriptfiles" tal:repeat="jsfile
javascriptfiles">
<script type="text/javascript" src="${jsfile}"></script>
</tal:block>
but that also gives an error.
Am I taking the wrong approach, or is there a solution?
